Continuous split flow-thin cell fractionation of starch particles

The fractionation of starch granules was investigated using a SPLITT (split flow-thin) cell, a relatively new system for fast, continuous binary separ ations. The effect of such basic separation parameters as carrier compositi on, relative flow-rates and sample concentration on the SPLITT cell perform ance were exploited. The obtained starch fractions were checked by both opt ical microscopy and sedimentation/steric field flow fractionation (Sd/StFFF ). The sedimentation field flow fractionation technique was employed for th e starch sample using the density compensation procedure. (C) 1999 Elsevier Science B.V. All rights reserved.
